💡 Usage Tips

Before first use, please ensure the lock body has sufficient battery power. It is recommended to fully charge it before use.

If your phone does not have NFC functionality, you can attach the NFC card sticker to the back of your phone for convenient unlocking.

If not used for extended periods, please charge the lock every 3 months to avoid over-discharge and damage to the battery.

If the lock body surface becomes stained, wipe it with a dry or damp cloth. Do not use corrosive cleaning agents.
